We are bootstrapped, highly profitable, and fully remote team.
Our vision is to become the globally loved platform and community where traders master strategy, discipline, and growth.
We believe profitability stems from a repeatable process, disciplined execution, and continuous learning—TradeZella provides the tools and community to support this.
At TradeZella, we’re on a mission to empower 1 million retail day traders to become consistently profitable. That mission depends on building a fast, intuitive, and resilient product—powered by modern software practices and smart, efficient workflows.
As a Senior Full Stack Engineer, you’ll work across our stack to ship meaningful features, refactor core systems, and shape the technical foundation of our product. We’re looking for someone who thrives in a fast-paced environment, cares deeply about quality, and enjoys turning complexity into simplicity.
We're also embracing the future of development—AI-assisted tools like Cursor, GPT-based coding assistants, and natural language workflows are becoming part of how we work. If you’ve been experimenting with these tools and using them to improve your workflow, even better. We’re looking for a strong engineer who’s curious, adaptable, and always looking for an edge.
What You’ll Do:
- Ship full-stack features: Build and deploy end-to-end features across our Rails + React stack.
- Leverage modern tools: Use AI-assisted development environments (like Cursor) and prompt-based workflows to reduce boilerplate and move faster.
- Collaborate cross-functionally: Work closely with design and product to define scope, priorities, and the best UX for our users.
- Maintain quality: Write tests, improve coverage, and use AI-assisted QA or testing tools to catch bugs early.
- Contribute to architecture: Help shape the future of our platform as we scale to more users and more use cases.
- Improve systems: Refactor legacy code, enhance performance, and raise the bar for code quality and scalability.
- Experiment and share: Try new tools and workflows. Share what works with the team and help us stay ahead of the curve.
How You’ll Live Our Values
- Extreme Ownership: You take initiative, deliver outcomes, and follow through.
- Transparent Communication: You write clearly, share openly, and keep others in the loop.
- Bias for Action: You move fast and learn through doing.
- Excellence: You hold a high bar for your code and for your teammates.
- Customer Obsession: You build with empathy for our users—traders counting on us every day.
- Humility: You’re open to feedback and always looking to improve.
